' This inventionrelates to metal frames, as the metal frames for window sash and the like, and its object is to'provide a joint'between the frame rails where portions of the frame cross or meet each other which shall be of such construction that while the joint is'exceedingly strong it requires but simple operations both to form the parts necessary thereto and to establish the joint.

In the'drawings:

Fig. 1 shows a j oint-including fragment of a frame embodyingmy invention in; section on line 11,-Fig.4; r I

Fig. 2 is-a'similar view, with what I term the abutting rails separated from' what I term the through-rail;

"Fig. 3 isa section on line 33, Fig. 2; and Fig. at is a section on line-4 Fig. 1 before certain gibs are applied.

1 is the through-rail and 2 designates the abutting rails-arranged one on "each side of and each in a line-intersecting tliat of the through-rail. In the example each of the rails is angular (T-shaped) in cross-section, they are all of thesa-me cross-sectional dimen- V sions, and they". are all arranged with their bases (corresponding to the heads of "the TS) in the same plane. However, in all aspects of the invention these matters are not indispensable; nor is it indispensable in all aspects that there be two of the abutting rails.

- Each abutting rail 2 has a ton'gue 3 extending longitudinally from andintegral with its upright wall or web 2a, which'tongue is preferably fiat. Further, where as in the example there are two abutting rails, one on each side of the through-rail, the tongues thereofare preferably ofiset in opposite directions with respect totheir webs 2a, as by the 0 reverse bends at 3a, so that the said webs will then lie in the same plane (Figs. 3 and 4). The end of each abutting rail is to abut the through-rail 1 when the joint is established preferably both sides of (in Figs. 1 and 2,

5 above and below) its tongue, and if, as here,

said rail 1 is T-shaped in cross-section this is accomplished by forming said end with anabutting end face 4: on the base 26 of such 70 rail which is set back relatively to the end 5 face 5 on the web 211 and located at the relatively opposite side of the tongue.

Each tongue further has anopening here intheform of a slot 6 therein which is here V- shaped; each slot corresponds-with the other inform and relative position; i

The web 1a of the through-rall has an aperture 7 of such form as to-admit both tongues -snugly. i

Each tongue being entered into aperture 7 until the end of the corresponding rail '2 abuts rail 1, which when both tongues, are so 1 entered'will bring their slots into coincidence with each other, a gib 8 is driven into the slot at theside of rail-1 from which said tongue 110w protrudes; This gib is tapering and, whileits taper mayact to draw the corresponding rail 2 up firmly against rail 1 when the gib is entered, the taper serves to definitely limit the entering thereof. One edge of the gib liesface to face against the web of rail 1, and if at leastthe smaller end thereof, but preferably-both ends, are bent off toward that side of the slot 6 which forms an acute angle with the adjoining face of web 1a of rail 1 the gib will not only be h-eldin place 7 ,i but this bending thereof will cause it to wipe 'with pressure upon said face of webflaand augment any pressure of the end of the corresponding rail 2 with rail 1 which was obtained in the first instance by drivingin the j olb. I i I b The invention avoids any special forming ofthe rails beyond providing a slotted tongue on the abutting "rail and an aperture in the through-rail and employing a mere tapering gib as a locking device and it further makes it possibleto assemble the parts with facility and without the use of special tools.

vSo far as. I am aware it is new: in the art to provide a metal frame, of the class in V which a rail abuts one side of a through-rail and has a portion'thereof protruding through thethrough-rail and having an opening at itsother side, with a gib held in said open- "ingand having at least one end portion pro tr'uding therefrom and bent off toward and thereby jammed againstsaid other side of the through-member and I so claim broadly. V The method of securing to an apertured through-rail another rail an'gularly related to and abutting one side of the through-rail and having a portion thereof protruding through the through-rail and at its other side having an opening is also new which consists in securing a gib in the opening, causing the gib to contact only at its end portion With the through-rail, and straining the gib into jamming relation to the through-rail while so secured and contactin with the through-rail.

Having thus fully described my invention what I claim is 1. A metal frame including an apertured through-rail, another rail angularly related to and abutting one side of the through-rail and having a portion thereof protruding through the aperture of said through-rail and having an opening at the other side thereof, and a gib held in said opening and having one end portion thereof bent oii' toward and thereby jammed against said other side of the through-rail.

2. A metal frame including an apertured through-rail another rail angularly related to and abutting one side of'the through-rail and having a portion thereof protruding through the aperture of said through-rail and having an opening at the other side there of, and a gib held in said opening against turning on its own longitudinal axis and bent oif toward and having a surface lateral of the plane of bending thereof thereby jammed against said other side of the through-rail.

3. The method of securing to an apertured through-rail another rail angularly related to and abutting one side of the through-rail and having a portion thereof protruding through said through-rail and at the other side thereof having an opening, which consists in first securing a gib in said opening against turning on its own longitudinal axis and while they are so secured bending off an end-portion of the gib into amining relation to said other side of the through-rail.

4. The method of securing toan apertured through-rail.another rail angularly related to and abutting one side of the through-rail and having a portion thereof protruding through said through-rail and atthe other side thereof having an opening, which consists in first securing a gib in said opening against turning on its own longitudinal axis and while they are so secured bending off an end portion of the gib in a plane forming an acute angle with said other side of the through-rail and into jamming relation thereto.

5. The method of securing to an apertured through-rail another rail angularly related to and abutting one side of the through-rail and having a portion thereof protruding through said through-rail and at theother side thereof having a gib-receiving opening formed to confine thatportion of: a fiat gib which is immediately received thereby in a plane forming. an acute angle with a surface portion of said other side, inserting a flat gib in said opening and finally bending off an end portion of the gib into jamming relation to said surface portion.

6. The method of securing to an apertured through-rail other rails angularly related thereto and abutting opposite sides of the through-rail and protruding through the through-rail and having coinciding openings each side of the through-rail, which consists in. first securing gibsin said openings of both said other rails and one at each side of the through-rail-and each-against turning on its own longitudinal axis and while they are so secured bending off end portions of the two gibs into jamming relation to the respective sides of the through-rail.

7. A metal frame including an apertured through-rail, other rails angularly related to and having webs in substantially the same plane, each web having a tongue'integrally connected therewith and; protruding through the aperture of the through-rail and bent out of the plane of the web. and overlapping the other tongue, and ineansto secure the protruding portion of each tongue against withdrawal from saidaperture.

8. The method of securing toan apertured through-rail another rail angularly related to and abutting one side of the through 1'ail and having a portion thereof protruding through said through-rail and at the other side thereof having an opening which consists in securing a "gib inthe opening, causing the gib to contact only at its end portion with the through-rail, and straining the gib into jamming: relation to the through-rail while sosecured and contacting with the through rail. 7

9. The method of securing to an apertured through-rail another rail angularly related to and abutting one side of the through-fail and having a portion thereof protruding through said through-rail and at the other side thereof having anopeningwhich consists in securing a gib in the opening against turning 011 its own longitudinal axis, causing the gib to contact with the through-rail at a point through-rail while so secured and. contacting with the through-rail,

In testimony whereof I affix my signature.
